Why did I wait so long?

Power Play: Resistance by Rachel Haimowitz and Cat Grant 5*
BLURB:Give me six months, and I'll give you the world.
Brandon McKinney has scraped and sacrificed for what little in life he’s ever had. Though it’s been fifteen years since he escaped his father’s abuse, the damage remains. Trust seems as far out of reach as his dream of becoming an architect, and though he’s come to accept being gay, he can’t deny the shame and confusion he feels at other urges—the deeply-repressed desire to submit.
Jonathan Watkins is a self-made Silicon Valley billionaire whose ex-wife took half his money and even more of his faith. Comfortable as a Dominant but wary of being hurt again, he resorts to anonymous pickups and occasional six-month contracts with subs seeking only a master, not a lover.
When a sizzling back-alley encounter cues Jonathan in to Brandon’s deep-seated submissive side, he makes the man an offer: Give me six months of your life, and I’ll open your eyes to a whole new world. Brandon doesn’t care about that; all he wants is the three million dollars Jonathan’s offering so he can buy the construction company he works for. But he soon learns that six months on his knees is no easy feat, and shame and pride may keep him from all he ever wanted—and all he never dreamed he had any right to have.
My Review: I've had this book in my To-Be-Read pile (or at least on my reader) for a long while now, and after reading it, I cannot understand what took me so long to get around to it. It was a fascinating story with well written characters. A very in depth relationship, with faults on both sides that needed to be overcome, made for an emotional and exhausting read.
